Expedition 71 is the 71st long-duration expedition to the International Space Station. The expedition began with the departure of Soyuz MS-24 on 6 April 2024 [1] with cosmonaut Oleg Kononenko continuing his ISS command from Expedition 70. [2] [3] It will end with his departure on Soyuz MS-25 with crewmates from MS-24 and MS-25 on 24 September 2024. [4] [5]
Initially, the expedition consisted of Oleg, his Russian Soyuz MS-24 crewmate Nikolai Chub (both on a year long ISS mission since 15 September 2023), and his American Soyuz MS-25 crewmate, Tracy Caldwell-Dyson, who launched on 23 March 2024, as well as SpaceX Crew-8 crewmates, American astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, and Russian cosmonaut Alexander Grebenkin, who launched on 4 March 2024 and were transferred from Expedition 70 after Soyuz MS-24 departure. [5] [3] [6]
Later, the crew will be replenished by subsequent missions in both expedition and visiting crews in the expedition. [4] Boeing Starliner Crewed Flight Test (consisting of NASA astronauts, Barry Wilmore and Sunita Williams) is supposed to dock during the expedition. [7] [8]

Edward Michael "Mike" Fincke is an American astronaut who formerly held the American record for the most time in space. His record was broken by Scott Kelly on October 16, 2015.
Pirs(Russian: Пирс, meaning "pier") – also called Stykovochny Otsek 1 and DC-1 – was a Russian module on the International Space Station (ISS). Pirs was launched on 14 September 2001, and was located on the Zvezda module of the station. It provided the ISS with one docking port for Soyuz and Progress spacecraft, and allowed egress and ingress for spacewalks by cosmonauts using Russian Orlan space suits. Pirs was docked to Zvezda for almost 20 years, until 26 July 2021, where it was decommissioned and undocked by Progress MS-16 to make way for the new Nauka module.
Sergey Aleksandrovich Volkov is a retired Russian cosmonaut and engineer. He was a member of three missions to the International Space Station, spending more than a year in total in space. During his missions he did four spacewalks lasting more than 23 hours in total. Volkov retired from the Cosmonaut group in February 2017.
Kimiya Yui is a Japanese astronaut from the Japan Aerospace Exploration Agency (JAXA). He was selected for the agency in 2009.

Anatoli Alekseyevich Ivanishin is a former Russian cosmonaut. His first visit to space was to the International Space Station on board the Soyuz TMA-22 spacecraft as an Expedition 29 / Expedition 30 crew member, launching in November 2011 and returning in April 2012. Ivanishin was the Commander of the International Space Station for Expedition 49.
Andrew Richard "Drew" Morgan is a NASA astronaut from the class of 2013.
Expedition 52 was the 52nd expedition to the International Space Station. It officially began on June 2, 2017 10:47 UTC, with the undocking of Soyuz MS-03. Transfer of command from Expedition 51 was done on June 1, 2017.
Boeing Starliner-1 also called Post Certification Mission-1 (PCM-1) is planned to be the first operational crew mission of the Boeing Starliner to the International Space Station (ISS) as part of the Commercial Crew Program. It would be the fourth orbital flight mission of the Starliner overall. It is scheduled to launch no earlier than early 2025, transporting members of a future ISS Expedition.
Expedition 58 was the 58th expedition to the International Space Station, which began on December 20, 2018 with the departure of the Expedition 57 crew. It was commanded by cosmonaut Oleg Kononenko, with astronauts Anne McClain and David Saint-Jacques as flight engineers; the trio launched on board Soyuz MS-11 on December 3, 2018, marking the 100th orbital launch of the year.
Expedition 59 was the 59th Expedition to the International Space Station. It started with the arrival of the Soyuz MS-12 spacecraft carrying Aleksey Ovchinin, Nick Hague and Christina Koch, joining Oleg Kononenko, David Saint-Jacques and Anne McClain who transferred from Expedition 58. The expedition formally began on March 15, 2019. Ovchinin and Hague were originally meant to fly to the ISS aboard Soyuz MS-10, but returned to Earth minutes after takeoff due to a contingency abort. The expedition formally ended with the undocking of the Soyuz MS-11 spacecraft carrying Kononenko, Saint-Jacques and McClain on 24 June 2019; Ovchinin, Hague and Koch transferred to Expedition 60.
Expedition 60 was the 60th Expedition to the International Space Station, which began on 24 June 2019 with the undocking of the Soyuz MS-11 spacecraft. The expedition was commanded by Aleksey Ovchinin, who transferred from Expedition 59 together with American flight engineers Nick Hague and Christina Koch. They were joined by Aleksandr Skvortsov, Luca Parmitano and Andrew Morgan, who arrived on Soyuz MS-13 on 20 July 2019. The expedition ended on 3 October 2019, when Soyuz MS-12 undocked from the station and Koch, Skvortsov, Parmitano and Morgan transferred to Expedition 61.
Expedition 61 was the 61st Expedition to the International Space Station, which began on 3 October 2019 with the undocking of the Soyuz MS-12 spacecraft.

Parmitano, along with his Soyuz MS-13 colleagues Aleksandr Skvortsov and Andrew Morgan, and Christina Koch from Soyuz MS-12, transferred over from Expedition 60. They were joined by Oleg Skripochka and Jessica Meir, who launched on 25 September 2019 on board Soyuz MS-15.
Boeing Starliner Calypso is a space capsule manufactured by Boeing and used in NASA's Commercial Crew Program. On 20 December 2019, Calypso launched on the Boeing Orbital Flight Test mission, an uncrewed test flight of Starliner to the International Space Station. The spacecraft was scheduled to dock to the ISS and then return to Earth following a week in space, although due to several software issues the spacecraft was unable to rendezvous with the station and landed after two days in space, resulting in Boeing needing to schedule a second Orbital Flight Test.
The Commercial Crew Program (CCP) provides commercially operated crew transportation service to and from the International Space Station (ISS) under contract to NASA, conducting crew rotations between the expeditions of the International Space Station program. American space manufacturer SpaceX began providing service in 2020, using the Crew Dragon spacecraft, and NASA plans to add Boeing when its Boeing Starliner spacecraft becomes operational no earlier than 2025. NASA has contracted for six operational missions from Boeing and fourteen from SpaceX, ensuring sufficient support for ISS through 2030.
Expedition 68 was the 68th long-duration expedition to the International Space Station. The expedition began upon the departure of Soyuz MS-21 on 29 September 2022, with ESA astronaut Samantha Cristoforetti taking over as ISS commander, and ended upon the departure of the uncrewed Soyuz MS-22 spacecraft on 28 March 2023.
SpaceX Crew-5 was the fifth operational NASA Commercial Crew Program flight of a Crew Dragon spacecraft, and the eighth overall crewed orbital flight. The mission was successfully launched on 5 October 2022 with the aim of transporting four crew members to the International Space Station (ISS). The Crew Dragon spacecraft docked at the ISS on 6 October 2022 at 21:01 UTC.
